A titan, as defined by Samuel Yates, is anyone who has found a titanic prime . This page provides data on those that have found these primes. The data below only reflect on the primes currently on the list. (Many of the terms that are used here are explained on another page .)

AthGFNSv and the 64 bit program AthGfn64 are programs to
rapidly presieve Generalized Fermat candidates removing
composite numbers. AthGFNSv supports trial division for
small ranges and both programs support wide mode true sieve
for larger ranges. The 64 bit version is 60%-80% faster.
